On Friday, we learned about dilutions. You know if a problem on a test or quiz involves a dilution if the question starts and ends with the same solution. In a dilution, you regularly start with a a stock dilution and add water. With serial dilutions, you make subsequent solutions from an original stock by continuing to dilute it down. The amount of solution you move and add more water to each step is the aliquot.

To solve problems involving a dilution, you use the following equation:

Something to remember is that the V2 in the equation represents the total solution, which is the aliquot + the water used.
Here is a link to a couple websites where you can learn more about dilutions and use the dilution formula with practice problems:
Lilly, this was a great post talking about dilutions. I wasn't very clear on some aspects of this topic, but after this post it made much more sense. I enjoyed how you defined different parts of the dilution, and made it clear that they are each important to know. Also, including pictures that explain how it occurs and the math to do to go along with it made it easier to understand. In addition, your links to the worksheets were very helpful for practicing these problems! Thanks for this post!
